As of January 2009, roughly 20,000 organizations used Likewise's software to integrate Linux, Unix and Apple Macintoshes with Microsoft's Active Directory. But in September 2009, Likewise will take steps to educate the Ubuntu crowd by hosting a webinar specifically designed for Ubuntu users and administrators.

UPDATED AUGUST 27, 12:49 p.m. eastern: Please note that the webinar link above has been updated. Likewise revised the link to ensure Linux/open source users could be accommodated on the webcast.

I don't typically blog about vendor-hosted webcasts. But in this case, I think Likewise is making news by specifically reaching out to the Ubuntu community -- and to Windows administrators who may need to manage Ubuntu systems.
